' I Specification of Letters Patent.

Application filed July 10,1906. Serial No- 325,519.

To all whom it May concerns 7 Be itknown that I W NFIE D SISHELTQN, a clti'ze'n of the United States, residing at Jenisiana, have invented a new and useful Pump, 1 of which the following is -a specificat1on.

This invention relatesinore particularly to pumps of that character wherein rotary-pis tons are employed; and-one of the rincipal obj ects. is to. provide an exceeding y-siinple structure which will permit the ready removal of the piston without the necessity of dismembering the remaining portions of the ump. v

c A still further andimportant object 'isto provide novel pump mechanism that will ave a comparatively great capacity without materially increasing the size or bulk-of the same as a whole.

The preferred embodiment of the' vention is illustrated in the accompanying drawings, wherein j f Figure 1 is a perspective view of the pump, Fig. 2 is a vertical sectional view therethrough. Fig 3 is a sectional view at right Fig. 4 is ahorizontal sectional view through the piston member and ontheline i lofFig. 3.

Similar referencenumerals' designate corresponding parts in all the figures of the drawings. r

in the structure disclosed-a casing 5 is employed, which in the present embodiment consists of angularly-disposed upright walls 6. It will of course be'understood that the shape of this casing may be varied as desired. A piston-chamber 7 is located in the lower portion of the casing'and comprises a top wall 8 and a bottom wall 9, saidwalls be- 9 is disposed above a base 12, that constitutes the lowerend' of the casing and forms therewith a lower inlet 13, communicating with the piston member- 7 through the bottom opening 11L The side walls are provided with suitable openings 14, that permit the fluid to be elevated to flow freely intothe inlet 13 and thence into the chamber 7 An u per inlet 15 is'formed over the piston c amber 7 and opens, as shown at 16, through s1 e walls 17 of the inlet 15-are spaced from the other 0 posite side walls [of the casing communicating at their lower endswith the piston-chamber and discharging into the main body of the casing above the inlet 15. The inlet 15 is separated from said main portion of the interior of the casing by a partition comprising angularly-disposed sections 19, hinged'at their outer edges to theupper ends of the walls 17, the inner edges of the sections being abutted. The sections thus constitute supports for each other and are capable of swinging outwardly, as shown in dotted lines in Fig. 2', so as tothrow the inlet 15 into direct'communication. with theinte-- rior of the casing. Under ordinary conditlons, however, the sectlons are disposed in abutted relation, as shown in full lines in Fig. 2, in which case the inlet 15 is cut off from the interior of the casing. I

A driving-shaft 20 extends longitudinally down into ,the casing between the sections 19 and throu h the piston-chamber 7, said drivingrshaft eing capableof upward longitudinal movement. Mounted on this shaft and normally located in the piston-chamber is a piston, (designated as awhole by the ref erence-numeral 21.), The piston comprises an upper disk 22, provided with a central opening 23, a lower disk 24, provided with a central openin 25, and an intermediate disk 26, throughw ich the shaft snugly asses, said intermediate disk being preferab y provided with a hub 27, having a set-screw 28,

that engages the shaft. Interposedbetween and secured tdthe'different disks are outwardly-extending curved blades 29, that have their inner ends. terminating at the openings 23 and 24. The upper disk 22 is larger than the opening 10in t e upper chamber-wall 8 and covers the same. The opening 11in the lower chamber-wall 9 is smaller than the upper opening "10 and iscovered by the-lowermost disk 24;, said disk 24 overlapping the wall 9, as'shown in Fig. 2, and being of small enough diameter to pass freelythrough the upper chamber-wall opening 10.

The same is true of the intermediate disk 26.

With theparts assembled as shown in the drawings the operation of the structure may be briefly described as follows; The pump is placed in the liquid to be elevated until the level of the liquid is above the piston-chamber, or, in other words, until said liquid will flow freely into the upper inlet 15. If now the driving-shaft 20 is rotated in the proper direction, it will be evident that the liquid will be thrown outwardly in the piston-chamtion may be resorted to without connected to the ber and drawn inwardly through the central openings 23 and 25 of the piston. The liquid discharged from said chamber will be elevated through the channels 18 and on passing over the partition 19 will, fill the casing and discharge through the outlet 29. Inasmuch as the piston has a doubled inlet and a double set of upper and lower blades, it will be evident that its capacity is comparatively great, so that the pumpwill elevate a correspondingly great amount of liquid. At the same time the said piston is readily removable from the chamber, for upon raising the driving-shaft 20 this piston can pass freely through the inlet and upwardly into the casing, inasmuch as the partition-sections 19 will swing freely outwardly to permit the passage of said piston. It will be thus evident that the piston can be removed whenever desired without the necessity of dismembering the remainder of the structure. From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art Without further description, and it will be under-, stood that various changes in the size,| shape, proportion, and minor details of construcdeparting from the spirit or sacrificing any of the advantages oi the invention.

Having thus fully described-my invention, What I claim as new,- and desireto secure by Letters Patent, is
